- TIRE-WRAPPING MACHINE Specification of Letters Patent.

Patented Sept. 17, 1918.

Application filed November 18, 1916. Serial No. 182,165.

To all whom it may concern:

San Diego, in the county of San Diego and State of California, haveinvented new and useful Improvements in Tire-\Vrapping Machines,'ofwhi'ch the following is a specification.

This invention relates to tire wrapping machines in which a'rotatableannular shut- .tle is employed for carrying a spool or roll sary ordesirable to provide with a removable section, to the end that vehicletires may be properly positioned for the wrapping operation, after whichpositioning the removable section or gate is replaced to complete theannulus and, in some instances, facilitate driving the annulus at'the'periphery thereof.

In accordance with the present invention, an annular spool orroll-carrying shuttle having a removable peripheral segment is employed,and such segment and the remaining portion of the shuttle are soorganized that the segment may be readily removed and as readilyreplaced when such removal and replacement for the purpose'of changingtires becomes necessary; furthermore, means areprovided for clamping thesegment in position to complete the an nular form of the shuttle andrigidly bind the same to remaining portions of the annulus by a simplemovement of'one hand of the operator, and for removing the segment orgate by a similar motion. I

The invention has for a further object the provision of an'improvedshuttle and gate thereof which will berelatively simple and inexpensivein construction and organization when its features of superiority inpositiveness of action, freedom from liability to get out of order orrepair, and speed of operation are considered, and which will begenerally superior in efficiency and serviceability.

. A practical embodiment of my invention is represented in theaccompanying drawings in which,

Figure 1 represents a fragmentary side elevation of a spool orroll-carrying annulus and gate thereof for a wrapping machine organizedin accordance-with the invention,

parts being broken away and sectioned for clcarnoss of illustration;Fig. 2 represents a plan view of the features shown in Fig. 1, partsbeing broken away and. sectioned for clearness of illustratlong Fig. 3represents a dlagrammatic view of parts shown in the other figuresillustrating positions assumed by the parts, the view being taken on anenlarged-scale; and

Fig. 4 represents a diagrammatic side viewof a tire wrapping machineannulus and other features associated therewith showing a fragment ofthe-tire in position for wrapping or winding, the view being on agreatly reduced scale.

Referring with particularity to the drawing, A (Fig. 4) designates aframe portion of a tire wrapping machine, B-tho spoolcarrying shuttlethereof, C the gate, D rotating means for the shuttle and E a Vehicletire being wrapped.

The frame portion A conventionally illustrated in "the drawing comprisesa vertical part 5,' and a plurality of pulleys 6 sup-- ported thereon bymeans of shafts 7 upon which said pulleys are rotatably mounted and suchpulleys are arranged to support an endless belt 8, to which power may beapplied to rotate the. shuttle by frictional engagement with the latter.-A driven pulley 9 is provided for actuating the belt.

The shuttle B comprises a member 10 of suitable material (iron)supported for r0- tation in the frame part 5, and a gate 11 coactingwith the member 10 to complete the annular form thereof, andconstituting the member C. Themember 10 and the gate 11 when united formanannulus which may be'rotated by the application of power to theperiphery by the belt 8. To this end, a groove 12 is provided around thecircumference of the annulus andthe belt 8 is adapted to take into suchgroove and properly drive the annulus. The member 10 is provided at asuitable point interiorly thereof with an inwardly projecting bracket 13upon which is supported a roll or spool 14 of tape or the'like 14 whichis to be wound about a tire. The member 10 is further provided withinwardly projecting catches 15 disposed at opposite sides of the gatespace, and such catches may be arranged in-pairs two at each side of thegate opening. The catches may be formed of suitable flat material andlet into the member 10 by slotting the same as at 16, or the catches maybe Otherwise secured in positionbnthernember 10 or formed thereon in anypreferred manner. The catches 15 each have a rounded head portion 15 andan undercut portion as at 15", a projecting head with inclined wallsbeing thus formed as clearly illustrated in Fig. 1. The under faces thusformed on thccatch head 15 at 15 all face away from the gate opening inthe member 10 and are adapted to coact with latch features provided onthe ate.

The gate 11 preferably comprises a curved segmental portion 11 curved atits outer face to the same radius as is the outer face of the member 10,a plurality of oppositely operable latches 17, means for supporting andguiding said latches, one such means 18 being provided for each of thelatches, and means b for actuating the latches to draw the same or theheads thereof into engagement with the under faces of the catch heads 15on the member 10 and to move the same out of engagement with such faces.The means b for actuating the latches preferabl comprises an eccentricshaft 19, an eccentrlc 20 for each of the latches 17 mounted thereon, aconnecting rodor link 21 extending from each eccentric to the respectivelatch 17, and a lever 22 secured to said eccentric shaft to rotate thesame to throw the latches 17 into or out of engagement with the underfaces 15 of the respective heads 15 formed on the member 10. The latcheseach comprise a longitudinally movable shank portion 23 and a T-head 24formed thereon producing a T-shaped latch the lat erally extendingportions of which are each adapted for engagement with the lower surfaceof a head 15, the latch shanks lying between the catch heads 15. It willbe observed that the under faces 15 slant outwardly toward the gapadapted to receive the gate 11 and toward the periphery of the shuttleas a whole/so that, when the laterally extending portions 25 of thelatch heads are .drawn into engagenwnt with the said faces 15 by themeans which actuates the latches, the gate is forced outwardly towardthe periphery of the shuttle and into firm abutment therewith. The factthat the lines of severance between the gate and the remainder of theshuttle are oblique to the radii of l the shuttle as a whole, so as tocause the gate and its gap to be longer on the inside than on theoutside, also lends to the elfectuation of the said result. The supportsor guides 18 are each preferably formed of an inwardly ranging boss 18secured to the inner face of the curved segment 11 as by means of capscrews or the like 18", such bosses being apertured each to accommodatea latch shank 23. The bosses are of sufficient lengthto provide therequired wearing surface for the latch shanks. The connecting links 21are each formed with an eccentric strap 26 at one end, such strapencircling the respective eccentric, and the links are bifurcated attheir opposite ends as at 27 for connection with the inner ends of thelatch shanks 23 and are secured as by means of pins 28. The eccentricshaft 19 is mounted in suitably spaced inwardly facing lugs 19preferably integrally formed with a base plate l9 which is secured tothe inner face of the curved segment 11 as by screws or bolts 19. Theeccentrics are disposed on the shaft 19 in such a manner that theyproject in diametrically opposite directions and the operating lever orhandle 22 is fixed to the shaft at a suitable angle to said eccentricsso that they may be conveniently actuated thereby and the handle, whenthe latches are in catch head engaging position, may lie close to theannulus. The guide bosses 18 are formed integrally with fastening plates18 and said plates are each provided, with projections 18 which restupon the inner surface of the annular member 10 when the gate is inposition, the gate being formed to exactly fit the gap provided thereforin the annular member 10.

The tire E is shown as lying in a plane at right angles to the plane ofrotation of the shuttle and, as wrapping proceeds, succeeding tireportions may be presented to the wrapping zone at the axis of therotatsame as the tire is rotated.

The operation, method of use and advantages of the improved wrappingmachine and the gate features thereof, will be readily understood-fromthe foregoing description, taken in connection with the accompanyingdrawing and the following statement:

The gate. being removed a tire may be placed in position for wrapping byintroducing a portion of same into the shuttle through the open portionin the member 10, after which the gate may be laced in position and thelever 22 presse outwardly to draw the eccentrics in the proper directionto move their respective latches into engagement. with the catch heads15* at the under side thereof and so clamp the gate into position tofill the gap or open portion in the member 10, the projecting portions18 restin on the inner surface of the member 10. fiy exerting slightpressure on the positioned the shuttle ntay be rotated and the tiretaped or wound, after which the gate ma y be removed by merely throwingthe lever '22 inwardly away from the gate, thus forcing the latchportions 22 out of engagement with the surfaces 15 o'f the catch-'heads, when the latch headswith the gate may b lifted out of positionin the mem-;

ber 10. A suitable knob a maybe provided n theinner side of one ofthebosses 18* to afford a hold for the hand of an operator in removingorreplacing the gate; Aftpi the gate has been moved from its positlon-mth opening, it being understoodth at the.

to clamp and bindjthe same to the memin the claims.
